Modified H2S Paper Strip Test for Detection of Bacteriological Contamination in Drinking Water
The provision of safe drinking water to all is the priority item in the agenda of Government of India. To fulfill this requirement thousands of bore well installed in the villages. Despite of this, large population still depends upon the dug well water; shallow bore well and untreated surface waters for their drinking water needs. Hence there is need to monitor the bacteriological quality of wa...
متن کاملBacteriological quality of drinking water in Punjab: evaluation of H2S strip test.
OBJECTIVE To assess bacteriological quality of drinking water in Punjab and to evaluate usefulness of H2S strip test in comparison with multiple tube test. METHOD Samples of water were tested using H2S strips and multiple tube test. RESULTS Maximum bacterial contamination was observed in water from domestic pumps (95.83%). Followed by tap water in rural areas of Punjab (91.30%) and tap wate...
متن کاملThe role of faecal coliforms in water quality assessment
The paper aims to evaluate the role of faecal coliforms in assessment of water quality. The study was conducted on the Neretva River in Bosnia and Herzegovina. The sampling was performed bimonthly, over 12 months at seven selected sites. APHA (1995) methods were used. The raw data of temperature, pH, conductivity, oxygen saturation, nitrogen, total phosphorus, and faecal coliforms were transfor...
متن کاملInjured coliforms in drinking water.
Coliforms were enumerated by using m-Endo agar LES and m-T7 agar in 102 routine samples of drinking water from three New England community water systems to investigate the occurrence and significance of injured coliforms. Samples included water collected immediately after conventional treatment, during the backwash cycle, at various points in the distribution system, and 1 week after the break ...
متن کاملMolecular method for detection of total coliforms in drinking water samples.
This work demonstrates the ability of a bacterial concentration and recovery procedure combined with three different PCR assays targeting the lacZ, wecG, and 16S rRNA genes, respectively, to detect the presence of total coliforms in 100-ml samples of potable water (presence/absence test). PCR assays were first compared to the culture-based Colilert and MI agar methods to determine their ability...
